1'5 Claims. (Cl. 271-11) The present invention relates to information storage card processing apparatus; and itrelates more particularly to a feeding-stacking station which may be included in such apparatus, and which may be used to feed successively cards to a transport means in the apparatus, or to receive cards from the transport means.

The invention is primarily concerned with an improved feeding-stacking station which cooperates with the other components of the card processing apparatus, and which serves to hold the information storage cards in a stacked condition. In this way, the cards may be controllably fed to the transport medium when the station is in a feeding mode. The feeding-stacking station of the invention is also capable of receiving the cards from the transport medium when the station is operated in a stacking mode.

The feeding-stacking station constituting this invention is of the magazine type in which the information storage cards in the station are stacked in a removable magazine. This arrangement permits a group of cards to be conveniently inserted in the station for processing, and it also permits the group of cards to be conveniently removed from the station at the termination of such processing.

The term information storage card is intended to be used in a generic sense in the present specification and claims. This term is intended to cover any discrete element on which the information may be appropriately recorded. Such discrete elements may include, for exam ple, plates, boards, panels and the like.

in one type of data processing system, information is stored in digital form on a plurality of separate cards. Each of the cards is provided with a number of posi tions, each of which for example is capable of storing a dilferent multidigit binary number. The information may be stored in the form of discrete magnetic areas of one magnetic polarity or the other, as is the case with the embodiment of the invention which will be described.

Alternately, the information may be stored in the formof hole patterns in the cards, in the form of photographic representations, or in any other appropriate form. It will be appreciated that for these various recording forms, it is merely necessary that the apparatus include appropriate transducers for transforming the information into electrical signals and vice versa.

A large number of information storage cards of the type discussed in the preceding paragraph are often required in complex data processing systems. This is because millions of bits of binary information are required to represent the information stored in the more complex data processing systems. It is most essential, therefore, in such data processing systems to provide some means for storing the cards themselves in a manner in which they may be quickly and conveniently fed to the card processing apparatus.

In one type of prior art card processing apparatus, for example, the information storage cards are maintained in stacked relationship in a card feeding station,

and the cards in the card feeding station are controllably fedin succession from the station to an appropriate transport medium. The cards are then carried by the transport medium in the prior art apparatus past a transducer station at Which the information on the cards is read and transformed into electrical signals, or at which new information is written-on the cards from input electrical signals.

To provide flexibility in the card processing apparatus of the type under discussion, it is preferable that the card feeding stations be of the reversible type. That is, each of the card feeding stations should also be capable of stacking operations. To that end, each of the stations should be able to operate in a first mode in which cards may be controllably fed from the station in sequence to a transport medium. Each of the stations should also be capable of operating in a second mode in which cards may be removed from the transport medium and sequentially deposited in the station. Such reversible feeding-stacking stations are described and claimed, for example, in copending application Ser. No. 53 8,111 filed October 3, 1955, in the name of Robert M. Hayes (now United States Patent No. 2,842,362), and in copending application Ser. No. 645,639 filed March 12, 1957, in the name of Alfred M. Nelson et al.

A certain problem is sometimes encountered in the reversible card feeding-stacking stations discussed above, and in other types of feeding-stacking stations included in the card processing apparatus. This problem concerns the provision [of a convenient means for inserting a stack of cards into the feeding-stacking station for processing, and for permitting the convenient removal of the stack of cards from the station at the termination of such processing.'

The large number of cards involved in the more com pleX card processing system usually require that the cards not actually being processed be stored in an appropriate file block separate from the card processing apparatus. Then, when any particular group of cards is to be processed, that group is removed from the file block and inserted in one of the feeding-stacking stations of the card processing apparatus. This enables the cards of that particular group to be processed, and at the termination of such processing the group of cards is returned to the file block and another group may then be inserted in the station to be processed.

copending application Ser. No. 685,539, filed September 23, 1957 (now United States Patent No. 2,901,247), in the name of Allan Orner discloses and claims an improved card processing apparatus in which the different groups of cards are held in individual magazines, with each magazine holding its group of cards in a stacked condition. The magazines can be conveniently stored in a separate tile block, such as referred to in the preceding paragraph. The magazines may then be individual- 13 removed (either mechanically or manually) from the storage area and placed in a feeding-stacking station of the card processing apparatus whenever a desired group of cards is to be processed.

The improved card processing apparatus of the copending application Ser. No. 685,539 (now United States Patent No. 2,901,247), is constructed so that a selected magazine of cards may be quickly snapped into place in a feeding-stacking station in a position to permit the cards immediately to be fed in succession to the card processing apparatus. The construction of the apparatus of the copending application is such-that the magazine can be inserted and Withdrawn from the feedingstacking station without interfering in any manner with the card transfer control components of the feedingstacking station.

Copending application Ser. No. 767,132, filed Octo- 3 her 14, 1958, in the name of Alfred M. Nelson et al., also is directed to card processing apparatus in which removable magazines may be inserted and withdrawn from the feeding-stacking stations. In the magazine used in the apparatus of that application, each magazine is provided with a closure member at its forward end and with a spring-biased card follower for urging the stack of cards forward in the magazine and towards the mouth of the magazine.

The magazine of the apparatus described in the copending application Ser. No. 767,132 referred. to in the preceding paragraph is supported in. its feeding-stacking station in a position spaced from the transport medium. This is so that the magazine will not interfere with the card transfer components of the feeding-stacking station, as these components are moved from one position to another when the feeding-stacking station becomes conditioned from any one of its twooperating modes to the other.

An appropriate mechanism is provided in the copending application Ser. No. 767,132 referred to above for opening the closure member of the magazine when the magazine is placed in the feeding-stacking station. Then, when the closure member is opened, the spring-loaded card follower in the magazine forces the cards out of the mouth of the magazine and against the transport medium. The card follower is positioned behind the stack of cards in the magazine so that it may accomplish this purpose. A guide member is permanently positioned in the feedingstacking station to guide the stack of cards so pushed out of the magazine into a proper position against the transport medium for the successive feeding of the cards to that medium.

The present invention is also concerned with the magazine type of card processing apparatus, such as the apparatus described in the preceding paragraphs. In the apparatus of the present invention, the spring-biased card follower is controlled to perform a dual function. The second function performed by the card follower, in addition to the function described in the preceding paragraphs, is that of firmly retaining any number of cards in the magazine after the magazine has been removed from the feeding-stacking station.

When the magazine is in place in a feeding-stacking station in the apparatus of the present invention, the cardfollower moves with the spring-biased action described above to urge the cards out of the mouth of the magazine and to hold the cards in the magazine in a stacked condition against the transport medium.

However, when the magazine is removed from the feedhag-stacking station, the card follower in the apparatus of the invention immediately locks at the last position in the magazine which it occupied just before the magazine was removed. The card follower now holds the cards firmly in a stacked condition against the closure member, or other card retaining means, at the mouth of the magazine.

The apparatus of the invention solves a problem which has been at times troublesome in the prior art. That is the problem of holding the cards firmly in the magazine when the magazine is withdrawn from the feedingstacking station. The problem is also concerned with providing the desired biasing effect on the cards whereby the cards are urged towards the mouth of the magazine when the magazine is inserted into the feeding-stacking station.

In the improved apparatus of the invention, immediately upon the insertion of the magazine into the feeding-stacking station, the card follower is released and it moves under its spring-biased pressure towards the mouth of the station. This spring-biased pressure of the card follower causes the cards in the station to be biased in a stacked condition towards the mouth of the station and against the transport medium for the successive feed of the cards to the transport medium. This spring-biased pressure of the card follower also provides for the retention of the cards in a stacked condition as they are fed, during a stacking operation, from the transport medium to the station.

Then, whenever a magazine is removed from a feedingstacking station, the card follower is immediately locked in the magazine to firmly hold the cards when the magazine is returned to the file block. This provides for the firm retention of any number of cards in the different magazines when the magazines are in the file block, and when the magazines are moved from the file block to the feeding-stacking station or from the feeding-stacking station to the file block.

Figure 8 is a perspective view of the magazine of Figure 1, illustrating that magazine positioned in its corresponding feeding-stacking station but with certain stop members removed to reveal the slide members in their extended positions, and illustrating the engagement of other components in the magazine with corresponding components in the station.

The data processing apparatus and system of Figure l is shown as including a transport medium such as a vacuum transport drum 10. This drum is constructed, for example, in the manner described and claimed in copending application Ser.'No. 600,975 (now United States Patent No. 2,883,189) which was filed July 30, 1956 in the name of Loren R. Wilson. The drum is rotatably mounted on a table top 12 for rotation in a clockwise direction. The drum is capable of exerting a vacuum pressure at its peripheral surface, and it is by means of this vacuum pressure that the information storage cards are held at spaced angular position on .the peripheral surface and the drum for transportation from one station to another. Full details of a rotatable vacuum pressure transport drum, such as the drum 10, may be found in the Wilson application referred to above.

Although rotatable vacuum pressure transport drums, such as the drum 10, are shown for transporting the cards, any other suitable transport means may be used and such transport means do not necessarily have to be movable. For example, stationary transport means such as disclosed in copending application Serial No. 730,102 filed April 22, 1958 in the name of 'Eric- Azari et al.; and in copending application Serial No. 731,413 filed April 28, 1958 in the name of Eric Azari may be used.

A first transducing means 14 is mounted on the table top 12, and that transducing means is positioned to be contiguous to the periphery of the vacuum pressure transport drum 10. A second transducing means 16 may also be mounted on the table top 12. This second transducing means is positioned on the opposite side of the drum 113 from the transducing means 14, and the transducing means 16 is also positioned to be contiguous to the periphery of the drum. Each of the transducing means 14 and 16 may, for example, comprise a series of electromagnetic write or read transducer heads. Each of these heads is positioned to sense and process a different row of data on each of the cards transported on the periphery of the transport drum past its corresponding transducer means.

The transducer means 14 and 16 are positioned to permit the cards to be carried past their activated faces by the transport drum 1%. Each of these transducer means functions to read data on the transported cards, or to write new data on the cards, as mentioned above. Also, and as also mentioned above, the type of transducer means corresponds to the particular type of recording by which the information is stored on the different cards. I

A first reversible feeding-stacking station is indicated generally as 18, and this station is positioned on the table top 12 at one side of the drum between the transducing means 14 and 16. A second reversible feedingstacking station 29 is also positioned on the table top 12, the station 29 being positioned on the opposite side of the drum 10 from the station 18. stacking stations 18. and 26 are shown in fragmentary form to conserve space. The forwardend of each of these stations only is shown, as such a showing is believed to be sufiicient for purposes of explaining the operation of the present invention.

The station 18 includes a stack head 22 and it includes a feed head 24. These heads may be constnucted and controlled in a manner fully described in the copending application Ser. No. 645,639 referred to above. Briefly, the stack head 22 is movable from a stand-by position to the right in Figure l, as illustrated, to an operative position in which its end is contiguous to the periphery of the drum 10. In its operative position, the stack head engages cards transported on the peripheral surface of the drum and causes such cards to be moved from'the peripheral surface of the drum and to be deposited in the station 18. t

The feed head 24 is movable from a stand-by position to the left in Figure l to its illustrated operative position. When the feed head is in its operative position it controls the feed of cards to the peripheral surface of the drum 16. This control is made through a vacuum pressure which the feed head exerts on the cards in the station, and which may be controilably interrupted. Such a feed head and its vacuum pressure control on the cards is described in detail in the copending application Ser. No. 645,639 referred to above.

The copending application Ser. No. 645,639 also fully describes the manner in which the feed head 24 and the stack head 22 may be moved between their stand-by and operative positions. Because the actual controland operation of the feed head and of the stack head form no part of the present invention, it is believed unnecessary to describe in detail the manner in which these heads are controlled. It is believed suificient to state that the heads maybe conveniently controlled by mounting them on appropriate levers and by providing a cam control for the levers. Such a control'is described, for example, in the copending application Ser. No. 645,639, and it provides for one of the heads to be moved to its operative position as member ismoved to a stand-by position, and vice versa.

The feeding-stacking station 20 may also include a feed head 36 which is movable between an operative and a stand-by position, and it may include a stack head which likewise is movable between a'stand-by and an operation position. The stack head 40 and the feed head 38 may be similar to the corresponding heads 22 and 24 described above in conjunction with the feeding-stacking station 18. The heads 36 and 40 maybe controlled to be moved between their individual operative and standby positions in the same manner as described in the copending application Ser. No. 645,639.

As best shown in Figure 8, the table top '12 is provided with a groove at the station 13 for receiving a magazine 50. The magazine may have a rectangular configuration, and it is equipped with a pair of side walls 52 and 54. As best shown in Figures 2, 3 and 8, the inner surface of the side wall 52 is provided with an upper slot 56 and a lower slot 58. These slots extend lengthwise along the entire inner surface of the side wall 52. In like manner, the inner surface of the side wall 54 is provided with a slot which is aligned with the slot 56 in I the side wall 52, and which extends along the entire inner Both the feedingsurface of the side wall 54. A lower slot 62 is also formed in the inner surface of the side wall 54, and the latter slot is aligned with the slot 58 in the side wall 52 and extends along the entire inner surface of the wall 54.

A top panel 64 is inserted in the slots 56 and 6t and is attached to the side walls by welding, or by any other appropriate means. Likewise, a lower panel 66 extends into the slots 58 and 62, and the lower panel is attached to the side walls by welding, or by any other appropriate technique. The panels 64 and 66 form thetop and bottom of the magazine respectively. These panels, together with the side walls 52 and 54 cooperate to form an open mouth at the forward end of the magazine.

A pair of ribs 68 and 76 is formed on the inner surface of the upper panel 64, and these ribs extend in parallel relationship lengthwise along the panel. A similar pair of ribs 72 and 74 are formed on the inner surface of the lower panel 66, and these latter ribs extend in parallel relationship along the entire length of the lower panel. The ribs 68 and 70 are spaced and parallel to one another in the plane of the upper panel 64, and the ribs 72 and 74 are spaced and parallel to one another in the plane of the lower panel 66. The ribs .68 and 72 are axially aligned with one another, as are the ribs 7%) and 74. These ribs engage the edges of the cards which are to be held in the magazine, and they form guides for the cards as the cards are moved back and forth in the magazine.

An upper bracket 76 (see Figures 1 and 8) is afiixed to the top panel 64 of the magazine by welding, or by any other appropriate means. of finger elements '78 and 82 which extend outwardly from the mouth of the magazine and over the upper peripheral surface. of the drum 10. These finger-like elements have downwardly extending bent-over end portions which extend over the top edges of the cards transported by the drum to the mouth of the station.

A similar bracket 64 is mounted to the underside of the lower panel 66, and the latter bracket has a pair of finger- The bracket 76 has a pair like elements 86 and 88 which extend outwardly from the mouth of the magazine and under the rim of the transport drum 111. The fingers 86 and 88 have bent-over ends which extend up over the lower edges of the cards transported by the drum to the mouth of the magazine.

The finger-like elements 78, 32, 36 and 88 permit the mouth of the magazine itself to be spaced back from the peripheral surface of the drum 1%, so that the feed head 24 and the stack head 22 may be moved between their operative and stand-by positions without interference by the walls of the magazine. The finger-like elements extend outwardly over the cards which are disposed in the space between the mouth of the magazine and the periphery of the drum 10, as such cards are successively fed from the magazine in sequence to the periphery of the drum during a feeding mode of operation; or when such cards are fed from the periphery of the drum into the magazine during a stacking mode of operation.

Then, when it is desired to withdraw the magazine from the station, the bent-over portions of the finger-like elements engage the card actually on the periphery of the drum 1t) and draw that card, and the cards in the space between the mouth of the magazine and the periphery, away from the drum. The bent-over finger-like elements, and certain sliding elements (which will be described) cage the cards at the forward end of the magazine as the magazine is withdrawn from the station. These elements firmly retain the cards in the magazine so as to prevent them from falling out of the magazine.

A card follower 1% (Figures 3 and 4) is positioned in the magazine for longitudinal movement along the ribs 72 and 74 towards the mouth of the magazine and back away from the mouth. The card follower 100 may be constructed in the manner described in copending application Serial No. 717,270, filed February 24, 1958, in the name of Eric Azari et a1. It is spring-biased towards the mouth of the magazine, and its function is to maintain the cards in a stacked condition in the magazine and to urge the cards against the peripheral surface of the transport drum 10. Then, as the cards are sequentially fed to the periphery of the drum, the card follower 100 is moved forward in the magazine by its spring-biasing pressure. Conversely, when the cards are stacked from the drum in the magazine during a stacking mode of operation, the card follower 100 moves back against its spring-biasing pressure. During both modes of operation, however, the card follower is forced against the rear of the stack of cards in the magazine to hold the cards in a stacked condition.

The card follower 100 includes a flat bottom panel 102 which may have a lubricating substance, such as Teflon, secured to its lower surface and which engages the ribs 72 and 74. A first guide strip 104 is secured to one side of the bottom panel 192, and this guide strip extends into a slot 106 which is formed on the inner surface of the side wall 54. The slot 106 extends for the length of the side wall 54, and it serves as a guide for the card follower 101).

The bottom panel 102 of the card follower also has a pair of elongated members 198 and 110 secured to its opposite edge. These latter members serve as guide strips and are disposed adjacent a slot 112 which is formed in the inner surface of the side wall 52. The latter slot extends lengthwise along the entire length of the inner surface of the side wall 52.

A resilient pad 114 formed, for example, of sponge rubber or similar substance, is secured to an upstanding bracket 116 at the front of the follower 100. As illustrated in Figure 4, the bracket 116 and the member 114 are inclined when viewed in plan so that the cards may be brought into the proper position for feeding them to the periphery of the drum 10, when the station is conditioned to the feeding mode.

A pair of electric switching contacts 118 are secured to the bracket 116 by a pair of screws 120. These contacts are short-circuited with one another, and they serve to engage a pair of further electric switching contacts on the face of the feed head 24 when the last card is fed out of the station 18. This completes an appropriate electric circuit, and under the control of appropriate logic circuitry, certain desired controls may be initiated after the station is empty. For example, when the station is empt it is desirable to change its mode of operation from the feeding mode to the stacking mode, so that cards now in the station 20, for example, maybe fed from that station and returned to the station 18.

The bottom panel 192 of the card follower 101) has a slot 124 formed in it adjacent the guide strips 108 and 110.. A bearing 126 is rotatably mounted on an appropriate bracket to be disposed over the slot 124-. A resilient spring strip 128 is secured to the panel 66 at its forward end, and this spring strip has a tendency to curl up on itself around the rotatable bearing 126. This action of the. spring strip 128, and of the bearing 126, causes the card follower to be biased forwardly towards the mouth of the magazine, for the reasons described above.

The upstanding bracket 116 is equipped with a pair of upwardly extending portions 139 and 132 (Figure 3). These portions 131) and 132 engage the ribs 68 and 70 respectively. A guide rail 134 is inserted inthe lower panel 66, and this guide rail extends into a slot formed in the bottom of the panel 162. Therefore, the springbiased card follower is supported between the ribs 68, 72 and'70, 74 and by the guide bracket 1% and its guide slot 165, and by the guide rail 134 and its corresponding slot inthe bottom panel 1132. The card follower lfitl is supported in this manner for longitudinal movement in the magazine toward and from the mouth of the magazine. As mentioned above, the spring strip 128 serves to bias the follower towards the mouth of the magazine.

An elongated locking bar 1'59 is mounted in the channel 112 of the side rail 52 to lie adjacent the edges of the elongated members 108 and 111 The outer edges of the members 108 and may be knurled, as may the facing edge of the locking bar 150. As will be described in more detail subsequently, the locking bar 151) is mounted in the slot 112 for limited longitudinal movement relative to the side wall 52. The arrangement is such that when the locking bar is moved forwardly in the slot 112, it moves laterally away from the members 108 and 111) to a disengaged position. However, when the looking bar 150 is moved back along the slot 112, and it is moved laterally inwardly so that its inner edge engages the facing edges of the members 1118 and 1119. This latter movement of the locking bar 150 is into an engaged position with respect to the card follower 109. When the locking bar 150 is in such an engaged position, it firmly retains the card follower 100 in whatever position the card follower isestablished by the stack of cards in the magazine when the locking bar 15*) moves to its engaged position.

As more clearly shown in Figure 5, the locking bar 150 is retained in the channel 112 by means of a plurality of upstanding studs, such as the stud 154. These studs extend through inclined slots, such as the slot 156, which are formed in the locking bar. A suitable resilient spring, which will be described in conjunction with Figure 6, serves to normally bias the locking bar 15% towards the rear of the magazine. Such biasing action causes the studs 154 to engage-the sides of the slots 156, so that the locking bar 150 is moved against the members 108 and 110 of Figure 4 to engage those members and thereby to lock the card follower 100.

As shown in Figure 5, a projection is formed on the side wall 52 of the magazine, and a pawl 162 is mounted in the station 18. ,The pawl has a portion eX- tending through a slot in the magazine to'be engaged by the projection 160 as the magazine is moved intoplace tion 160, it moves against the further pawl 164 and rotates the further pawl in a counterclockwise direction against its spring-biased pressure. The further pawl 164 has an actuating arm 166 which extends through a slot in the magazine and into engagement with a shoulder 168 formed in the side of the locking bar 150.

The result is that when the magazine is moved into place in the station 18, the projection 160 moves against the pawl 162 and causes the pawl 162 to move against the pawl 164. The pawl 164 is thereby rotated in a direction such that its actuating arm 166 causes the locking bar 150 to be moved forward towardthe mouth of the magazine. This action serves to disengage the locking bar from the card follower 100. Conversely, when the magazine is moved back out of the station 18, the locking bar 150 becomes disengaged from the arm 166 of the pawl 164 and it is spring-biased back into locked engagement with the card follower 100.

The operation described above provides that whenever the magazine is placed in the station 18, its card follower 108 is freed and spring biased towards the mouth of the magazine. This permits the card follower to perform its intended function of maintaining the cards in the magazine in a stacked condition against the peripheral surface of the transport drum 10. However, whenever the magazine is removed from the station, and regardless of the number of cards in the magazine, the card follower immediately becomes locked against the stack of cards in the magazine firmly to retain the cards in the magazine, and to prevent the cards from falling from the magazine when the magazine is in the file block, or as the magazineis moved to and from the file block.

As shown in Figure 1, for example, a stop member 170 is positioned in the station 18 adjacent the leading edge of the side wall 52 of the magazine when the magazine is moved into position in the station 18. The stop member 170 has an extremity 172 which is precisely positioned adjacent the periphery of the drum 10. The extremity 172 defines a feed throat with the drum 10, and it permits one card at a time only to pass the station onto the periphery of the drum.

The station 18 is illustrated in Figure 1 as being in its feeding mode of operation. For that mode of operation, the stack head'22 is withdrawn to a stand-by position, and the feed head 24 is moved to an operative position. A vacuumpressure is established at the face of the feed head 24, and that facev engages the leading card in the station 18. The vacuumpressure exerted at the periphery of the drum also acts on the leading card, but the former vacuum pressure is greater so that the feed head 24 holds the card in the station 18. However, whenever the vacuum pressure at the face of the feed head 24 is interrupted, the cards pass in a one-by-one sequence through the feed throat formed by the extremity 172 of the stop member 170.

As best shown in Figures 2, 6 and 7, a pair of elongated slide members 174 and 176 are positioned in slots 178 and 180 formed in the inner surfaces of the side walls 52 and 54 respectively. These slide members 174 and 176 are spring-biased in a manner to be described, so that they normally extend adjacent the mouth of the magazine beyond the ends of the side walls 52 and '54 to the position illustrated in Figures 5, 6, 7 and 8. When the slide members 174 and .176 are in their extended positions,

10 their extremities extend into the plane of the ends of the finger-like elements 78, 82 and 76, 88,

The slide members 174 and 176 serve to cage the leading cards in the magazine when the magazine is withdrawn from the station 18. These cards are rigidly retained in the magazine between the bent-over extremities of the finger-like elements 78, 82, 86 and 88 and the locked card follower 100. At the same time, lengthwise movement of'the cards is prevented by the slide members 174 and 176 in their extended position. The constructional details of the slide members 174 and 176 will be described in more detail in conjunction with Figures 6 and 7, and the action of the slide members is fully described and claimedin copending application Serial No. 829,430, filed July 24, 1959.

When the magazine is moved into position in the station 18, a stop member 184, which is mounted in the station 18 adjacent the feed head 24, engages a shoulder on the slide member 176 and forces that slide member to a retracted position back into the slot 180 against the pressure of its'biasing spring. This occurs because the slide member is held stationary by the stop member 184 as'the magazine is moved forwardly into position in the station. However, when the slide member 176 is in its retracted position, a portion 176aVof the slide member extends out from the mouth of the magazine, as shown in Figure 1, into a position closely adjacent the feed head 24. This protruding portion 176a of the slide member 176 has a cammed inner surface which is inclined slightly inwardly and serves to shift or cam the cards in the station laterally to the right intoan appropriate feeding position with respect to the feed head after the magazine. The end of the slide member 174, on the is in place. other hand, engages the stopmember 170, and the latter slide member is forced entirely back into its slot 178 to a retracted position when the magazine is moved into place. Here, the stop member 170 holds the slide member 174 stationary as the magazine moves forwardly into position.

As best shown in Figure 6, the locking bar is posi tioned in the slot 112 in the inner surface of the side wall 52 by a plurality of studs 154. These studs, as explained on conjunction with Figure 5, extend through inclined slots in the locking bar, so that the locking bar moves laterally in and out of an engaged position, as the bar is moved longitudinally in the slot 112. A bias spring 200 is mounted on the rear end of the locking bar 150. One end of this spring abuts against a washer 2112 which, in

turn, engages a shoulder at therear end of the slot 112.

The other end of the spring 200 engages a washer 204 which is welded, or otherwise mounted, on the end of the locking bar 150, This spring 200, therefore, serves normally to bias the locking bar 150 towards the rear of the magazine and into its engaged position with respect to the card follower 100.

As also shown in Figure 6, the slide member 174-is positioned in its slot 178m the side wall 52-by means, for example, one of the studs '154 and by a stud 208. These studs extend through appropriate slots which extend longitudinally in the slide member 174. A spring 210 is positioned on the slide member 174, and one end of the spring bears against a washer 212. The washer 212, in turn, abuts against a shoulder formed in the side wall 52. The forward end of the spring 210 abuts against a washer 214 which is welded, or otherwise mounted, on the slide member 174. Therefore, the slide member 174 is normally biased to its protruding position shown in Figure 8. However, when the magazine is inserted into place, as shown in Figure 1, this bar is forced back into its slot by the stop member by holding the bar stationary as the magazine is moved forwardly.

As shown in Figure 7, the slide member176 is mounted in its slot 180in the sidewall 54 by a pair of studs 220. These studs extend through appropriate longitudia slo n e s d me e 176 n the pe m t m- 1'1 ited movement of the slide member 176 with respect to the side Wall 54. A spring 222 is mounted on the slide member 176, and the rear end of that spring abuts against a washer 224 which, in turn, abuts against a shoulder formed in the side wall 54. The forward end of the spring 222 abuts against a washer 226 which is mounted on the slide member 176. The spring 222, therefore, serves to bias the slide member 176 to its protruding position as shown in Figure 8. However, when the magazine is moved into place in the station 18, the stop member 184 forces the slide member 176 back to the position illustrated in Figure 1 by holding the slide bar stationary as the magazine is moved forwardly. As mentioned above, the structural composition and operation of these slide members and their associated components are fully describedin the copending case Serial No. 829,430.

The invention provides, therefore, a new and improved feeding-stacking station of the removable magazine type. The removable magazine portion of the station of the invention is constructed and equipped, so that when it is removed from the station, the cards in the magazine are firmly retained and do not have any tendency to become loose or damaged in the magazine or to fall out of the magazine. When the magazine of the invention is placed into the'station, it is immediately placed in an operative condition, and the cards in the magazine are biased in the manner described towards the mouth of the station to be fed to the transport means, or to receive cards from the transport means. a
